Hello Spalding
Here’s an English guy who’s been using them for the last couple of years or more, they feature on his recordings Pavane and Aquarius, http://www.danielwatt.com/ also I notice there is a festival in Bewdley on the 4th July, you could give them a ring to see if they will let you in to have a listen. (It may be a closed festival though)
BTW Many Wersi Artists use Akai samples and VSTs both live and on recordings, (And have done so for many years) but you don’t notice because they integrate fully.
As I mentioned in a previous post, when my friend comes back off holiday I will see if I can get him to do some demos on his Scala using Akai samples and VSTs. Also check out to see if other Wersi artists are in your area, so that you can here the instruments close up. (Just do a quick search on the web)
Hope this helps.

Bill
